6 systemd_machined_selinux - Security Enhanced Linux Policy for the sys‐
7 temd_machined processes
8
10 Security-Enhanced Linux secures the systemd_machined processes via
11 flexible mandatory access control.
12
13 The systemd_machined processes execute with the systemd_machined_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep systemd_machined_t
20
21
22
24 The systemd_machined_t SELinux type can be entered via the systemd_ma‐
25 chined_exec_t file type.
26
27 The default entrypoint paths for the systemd_machined_t domain are the
28 following:
29
30 /usr/lib/systemd/systemd-machined
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 systemd_machined policy is very flexible allowing users to setup their
40 systemd_machined processes in as secure a method as possible.
41
42 The following process types are defined for systemd_machined:
43
44 systemd_machined_t
45
46 Note: semanage permissive -a systemd_machined_t can be used to make the
47 process type systemd_machined_t permissive. SELinux does not deny ac‐
48 cess to permissive process types, but the AVC (SELinux denials) mes‐
49 sages are still generated.
50
51
53 SELinux policy is customizable based on least access required. sys‐
54 temd_machined policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run systemd_machined with
56 the tightest access possible.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
67 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69
70 setsebool -P nis_enabled 1
71
72
73
75 The SELinux process type systemd_machined_t can manage files labeled
76 with the following file types. The paths listed are the default paths
77 for these file types. Note the processes UID still need to have DAC
78 permissions.

146 SELinux requires files to have an extended attribute to define the file
147 type.
148
149 You can see the context of a file using the -Z option to ls
150
151 Policy governs the access confined processes have to these files.
152 SELinux systemd_machined policy is very flexible allowing users to
153 setup their systemd_machined processes in as secure a method as possi‐
154 ble.
155
156 EQUIVALENCE DIRECTORIES
157
158
159 systemd_machined policy stores data with multiple different file con‐
160 text types under the /var/run/systemd/machines directory. If you would
161 like to store the data in a different directory you can use the seman‐
162 age command to create an equivalence mapping. If you wanted to store
163 this data under the /srv directory you would execute the following com‐
164 mand:
165
166 semanage fcontext -a -e /var/run/systemd/machines /srv/machines
167 restorecon -R -v /srv/machines
168
169 STANDARD FILE CONTEXT
170
171 SELinux defines the file context types for the systemd_machined, if you
172 wanted to store files with these types in a diffent paths, you need to
173 execute the semanage command to specify alternate labeling and then use
174 restorecon to put the labels on disk.
175
176 semanage fcontext -a -t systemd_machined_var_lib_t '/srv/mysystemd_ma‐
177 chined_content(/.*)?'
178 restorecon -R -v /srv/mysystemd_machined_content
179
180 Note: SELinux often uses regular expressions to specify labels that
181 match multiple files.
182
183 The following file types are defined for systemd_machined:
184
185
186
187 systemd_machined_exec_t
188
189 - Set files with the systemd_machined_exec_t type, if you want to tran‐
190 sition an executable to the systemd_machined_t domain.
191
192
193
194 systemd_machined_unit_file_t
195
196 - Set files with the systemd_machined_unit_file_t type, if you want to
197 treat the files as systemd machined unit content.
198
199
200
201 systemd_machined_var_lib_t
202
203 - Set files with the systemd_machined_var_lib_t type, if you want to
204 store the systemd machined files under the /var/lib directory.
205
206
207
208 systemd_machined_var_run_t
209
210 - Set files with the systemd_machined_var_run_t type, if you want to
211 store the systemd machined files under the /run or /var/run directory.
212
213
214 Paths:
215 /var/run/systemd/machines.lock, /var/run/systemd/machines(/.*)?
216
217
218 Note: File context can be temporarily modified with the chcon command.
219 If you want to permanently change the file context you need to use the
220 semanage fcontext command. This will modify the SELinux labeling data‐
221 base. You will need to use restorecon to apply the labels.
222
223
225 semanage fcontext can also be used to manipulate default file context
226 mappings.
227
228 semanage permissive can also be used to manipulate whether or not a
229 process type is permissive.
230
231 semanage module can also be used to enable/disable/install/remove pol‐
232 icy modules.
233
234 semanage boolean can also be used to manipulate the booleans
235
236
237 system-config-selinux is a GUI tool available to customize SELinux pol‐
238 icy settings.
